Precision carbide cutter for CNC wood and PVC work

This 4 mm diameter end mill is built for CNC operators who need clean compression cuts in wood, plywood, density board, solid wood and particleboard. The tungsten steel body carries a DLC coating that resists wear during extended routing sessions. Two up-cut and down-cut flutes shear material in both directions to prevent tear-out on the top and bottom faces.

Thermal and power behaviour in routing use

Carbide tooling runs cooler than high-speed steel when fed at recommended chip loads, reducing heat buildup in the workpiece and spindle. The DLC surface lowers friction so less cutting energy turns into heat, which also keeps the flutes sharper for longer. Normal CNC spindle power is sufficient; no special cooling or power upgrades are required.

Build integration and what it replaces

The 22 mm cutting length and 45 mm overall length fit standard ER collets and tool holders used on hobby and light-industrial CNC routers. It replaces worn compression bits without demanding a different holder or spindle interface. Buyers who need longer reach or larger diameters will need a different cutter; this tool is sized for the stated dimensions only.

Questions about this item

How do I install the 4 mm shank cutter in my CNC collet without causing run-out?

Insert the 4 mm shank fully into a matching ER collet, tighten the nut to the manufacturer's torque spec, and verify concentricity with a dial indicator before cutting.

When should I replace the DLC-coated carbide cutter?

Replace the cutter when the DLC coating shows visible wear, cutting edges chip, or finish quality drops on wood, plywood or particleboard.

What limits continuous cutting depth with the 22 mm flute length?

The 22 mm flute length sets the maximum single-pass depth; deeper cuts require multiple passes to avoid tool deflection and overheating.
